I have a 2010 Altima hybrid and usually get between 36 and 38 mpg combined city/highway (my calculations, not the computer's). At 35k miles so far and no problems. Not all hybrids are created equal. My electric kicks in under 40 mph and this car is pretty peppy compared to my mom's 07 Prius which is sluggish. This is my first CVT transmission and I'm liking it a lot. Overall best car I have owned so far although my past cars have been Buicks, a Pontiac, and a Ford Escort . I love new cars and tend to keep them close to ten years so we differ there.
